 ■ oblique tip, about 2 cm. long and 1.5 cm. wide, greatly inflated. 

 Flowers about 1.2 cm. long. Calyx black-hairy, teeth a fourth as long 

 as tube. Leaves about sessile, 5-7 cm. long. Leaflets 8-10 pairs, 

 oblanceolate. 1.5 cm. long. Stems ascending, a foot or two long. 

 Whole plant softly and rather s])arsely woolly. Bakersfield and Al- 

 calde California in open flats. Tropical. 



Astragalus lentiginosus var. scorpionis n. var. Pods coriaceaus,

Astragalus lentiginosus var. Idriensis Jones Cont. 10 63 (1902). 

 Pods lanceolate, often arched to a circle, about 2 cm. long, when not 

 greatly obcompressed the cross section is triquetrous-cordate, other- 

 wise rather ildymous and transversely linear. Flowers purple-tipped, 

 about 1.5 cm. long and very narrow, the wings and banner elongated, 

 and the keel normal that is half-spatulaite and the blade about 3
